    That is how the single phase motor on my air compressor smoked. Now I use a 3 phase motor with VFD.

    I appreciate your response because sometimes good advice falls on deaf ears. Well, maybe it's just good advice for me. At least you have a few options.
    You can read further and understand why I...

    Forget about the single phase stuff. The reason that you don't have real machinery power available in your location is because the housewife
    neighbors don't have 3 phase vacuum cleaners. So you have...

    You will just have to get all the options and costs and write it all down.

    Getting a motor re-wound is not that cheap. So I would buy a used 230v motor and fix that one up. And avoid the external...

    Well. you appear to know all the variables. I would add that the bastardization of a machine can be a one-way or two-way process.
    I would not alter a machine like this, but my observation is:

    The motor could be replace by a used one. Get a used one, install new bearings and paint the case. I've done this before.
    Otherwise if the motor is a special case then a rewind. There are articles...

    I learned from this forum that a 3 phase operation will appear to run smoother than a singled phase motor.
    In the sense of vibration and small variations that could make a cut look worse than it...

    That transformer is not useful, some of those Hammond transformers have more taps. My house wiring is 220V in and all 120V circuits are on one leg or the other.



    A RPC is the easiest. Build it...

    A 10Hp RPC is the thing to do, not go to 15Hp.
    A used 10Hp idler and a way to provide power to it. (Contactor, switch)

    Your control box is pretty slick and not that complex at all. And you want to do a single phase conversion to all that.:nutter:

    All your controls are 120V. If you built a 7.5-10hp RPC than you...
